In a single compartment cell fitted with a sacrificial magnesium anode, electrochemical reduction of phenyl and benzyl halides in the presence of trimethylchlorosilane gave the corresponding phenyl- and benzyl-silanes in satisfactory yields.Under well chosen conditions, the synthesis of phenyltrimethylsilane from phenyl bromide or chloride was also found possible.

Nickel-catalyzed decarbonylation of acylsilanes is developed. In sharp contrast to cross-coupling reactions of acylsilanes, in which the silyl group serves as a leaving group, the silyl group is retained in the product in this decarbonylation reaction. Although the strong binding of the dissociated CO to the nickel center frequently hinders catalyst turnover in nickel-mediated decarbonylative reactions, this reaction can be catalyzed by nickel complexes bearing a CO ligand.
Nickel-Catalyzed Selective Cross-Coupling of Chlorosilanes with Organoaluminum Reagents

, p. 3756 - 3759 (2019/09/12)
Nickel-catalyzed cross-coupling reactions of chlorosilanes with organoaluminum reagents were developed. An electron-rich Ni(0)/PCy3 complex was found to be an effective catalyst for the desired transformation. The reaction of dichlorosilanes 1 proceeded to give the corresponding monosubstituted products 2. Trichlorosilanes 4 underwent selective double substitution to furnish the corresponding monochlorosilanes 2. Overall, the selective synthesis of a series of alkylmonochlorosilanes 2 from di- and trichlorosilanes was achieved using the present catalytic systems.
